在在线 Python 平台（Jupyterlab online、Google Colab 等）中运行 Webdriver

Question

我可以在我的本地 python IDE 上运行 Selinium webdriver 来抓取网络数据，但我想在在线 python IDE 上实现它，例如 Jupyuter lab online 或 Google Colab，但是 chromedriver.exe 路径导致了一个问题在在线工具上，代码没有执行。我在 Jupyter lab online 和 google colab 上有以下代码：

import os
import sys
os.path.dirname(sys.executable)

from selenium import webdriver
browser = webdriver.Chrome(executable_path = '/home/jovyan/demo/chromedriver.exe' )

browser.get('https://www.youtube.com/')

I get the following error:

---------------------------------------------------------------------------

      1 from selenium import webdriver

      4 browser.get('https://www.youtube.com/' class="ansi-blue-fg">)

如果您有解决此问题的任何解决方案或任何其他 python 平台，请告诉我，因为我的项目的进一步部分取决于此 webdriver。

要在Google colab 中运行脚本，我总是使用下面的脚本，到目前为止还没有遇到任何问题。而且它只会出现在headless mode，没有 GUI。

你也没有像你在你的帖子中那样提供executable path。

!pip install selenium
!apt-get update 
!apt install chromium-chromedriver

from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
wd = webdriver.Chrome('chromedriver',chrome_options=chrome_options)
browser =webdriver.Chrome('chromedriver',chrome_options=chrome_options)
browser.get('https://www.youtube.com/')
